[Also in Divisions H1 and H3] An ignition system of capacitor discharge type comprises a plurality of semi-conductor switch devices 18 individually connecting the discharge capacitor 19 to ignition coil devices 16, individually coupled to spark devices 15, a rotary member rotatable with the engine and having a plurality of shaped pole elements arranged to co-operate with a pick-up device 50 for generating pulses in the pickup device when the pole elements pass the pick-up device, to produce firing pulses and a plurality of circuit portions arranged to individually connect the pick-up device to the semi-conductor switch devices. The circuit portions are responsive to a further pole element on the rotary member for completing the circuit portions to apply the firing pulses in turn to the semi-conductor switch devices so that the switch devices discharge the capacitor through the individual coil devices to provide timed ignition pulses to the spark devices. As shown the circuit portions include a plurality of reed switches 60 responsive to the further pole elements. In a modification the circuit portions include a plurality of semi-conductor devices in place of the reed switches.

Title: Improvements in or relating to electrical generating systems for automotive vehicles
IPC: H02J7/22
Filed: 1961-12-08
Abstract: 935,134. Self-contained supply systems, with variable-speed generators. FORD MOTOR CO. Ltd. Dec. 8, 1961 [Dec. 30, 1960], No. 43985/61. Class 38 (4). A supply system for a motor vehicle comprises an alternator 10 and rectifier 14 connected to a battery 37 and the electrical load 41 of the vehicle, a lamp 62 indicating whether or not the battery 37 is being charged. When the ignition switch 45 is closed, the coil 43 of a relay 42 is energized by the battery 37 to close normally-open contacts 53, 55 and energize the lamp 62 through normally-closed contacts 61, 65 also controlled by the coil 43. Closure of switch 45 also energizes the field winding 90 of the alternator 10 through the normallyclosed contacts 77, 84 of a double-contact voltage regulator 71 having a coil 72. When the rectified voltage of the alternator 10 is sufficient to charge the battery 37, the current through coil 43 is great enough to open the contacts 61, 65 and extinguish the lamp 62. Thereafter, when the alternator output voltage reaches a selected value, contacts 77, 84 are opened by the coil 72 to insert a resistance 95 in series with the winding 90 and the regulator 71 then operates in the usual way to control the alternator voltage at this value. The system may be modified by using a star-connected alternator and/or a positive earth. The construction and mounting of the relay 42 and regulator 71 is also described, Figs. 2-8 (not shown).

Compressive force applied across the two parallel faces 2, 3 of a block of solid (or laminated) magneto-strictive material is measured by the change in inductance of a winding 8 housed in a series of equally-spaced bores through the block. The bores run at right angles to the direction of the applied force. A pair of these transducers form two arms of an A.C. bridge to measure the inductance change. One of the pair may be unloaded and used to compensate for change in temperature &c., or the pair may measure forces in opposite directions, e.g. the thrust on a propeller shaft. A number of series-connected transducers may be used to support a container, Fig. 2 (not shown) so as to indicate its weight.

A remote control arrangement for a vehicle comprises a receiver in the vehicle which gives an electrical output in response to the reception of a signal modulated in a predetermined manner, means disabling a liquid fuel engine driving the vehicle in response to the output of the receiver, and a transmitter capable of transmitting the modulated signal. The transmitter may be at a fixed position or on another vehicle and is preferably directional. The radiation used is preferably infra-red and it may be modulated at a particular frequency. In one embodiment the radiation is received by lens 13, passed through filter 15 eliminating visible light, and falls on detector 17. The electrical output of the detector, if of the correct modulation frequency, is amplified by tuned amplifier 19 to operate relay 21. The contacts of the relay complete a circuit closing a valve in the fuel pipe of the vehicle. Preferably the valve includes a time delay device, such as a dashpot, which only allows the valve to re-open after a predetermined delay.
